Essential Fish Habitat
Essential Fish Habitat (EFH) was defined by the U. H. Congress in the 1996 amendments to the Magnuson-Stevens Fishery Resource efficiency and Management Act, or Magnuson-Stevens Act, as "those waters and substrate important to fish for spawning, breeding, nourishing or growth to maturity. "|1| Putting into action regulations clarified that marine environments include all aquatic areas and their physical, chemical, and biological properties; substrate contains the associated biological neighborhoods that make these areas suited to fish habitats, and the explanation and identification of EFH should include habitats used anytime during the species' life spiral.|2| EFH incorporates all types of aquatic habitat, just like wetlands, coral reefs, mud, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management local authorities to designate EFH using the best available scientific info. EFH has been described for more than a 1, 000 managed variety to date.|4| The key purpose of EFH regulations should be to minimize the adverse effects of fishing and non reef fishing impacts on EFH towards the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Work was amended to establish a brand new requirements to identify and express EFH to protect, conserve and enhance EFH for the main advantage of the fisheries.|5| The Magnuson-Stevens Act provides jurisdiction over the management and conservation of marine fish species. Federal agencies need to consult with NOAA Fisheries when their actions or actions may adversely affect habitat identified by federal territorial fishery management councils or perhaps NOAA Fisheries as EFH.|6| On Dec 19, 1997, interim final rules were published in the Federal Register (Vol. 62, No . 244) which stipulate procedures for implementation from the EFH provisions of the Magnuson-Stevens Act.|7| These rules were amended by publication of final rules on January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management system (FMP) amendment, and depth the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Influences from certain fishing techniques and coastal and marine development and may alter, harm, or destroy habitats important for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal organizations work together to minimize these risks.|13| Congress has established councils to classify unfavorable impacts on fishes in relation to types of fishing gear, coast developments and non-point and point source pollution, and also, evaluating how well each fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed variety. As new FMPs are developed, EFH for newly managed species will also be described.|14| FMPs must describe and identify EFH for the fishery, minimize to the extent practicable the adverse effects of fishing about EFH, and identify other actions to encourage the conservation and enhancement of EFH.
Through consultations, NOAA Fisheries can recommend ways federal agencies can avoid or minimize the adverse effects of their actions within the habitat of federally handled commercial and recreational fisheries.|16| Federal actions agencies which fund, permit, or carry out activities that may adversely affect EFH are required to consult with NOAA Fisheries.|17| The federal actions agency must provide NOAA Fisheries with an analysis of all actions or recommended actions authorized, funded, or perhaps undertaken by the agency which may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal action agency with EFH Resource efficiency recommendations.|19| These types of Conservation Recommendations provide information on how to prevent, minimize, mitigate, or counter those adverse effects.|20| Federal action agencies need to provide a written explanation to NOAA Fisheries if any of these recommendations have not been used.|21| NOAA Fisheries must also include measures to reduce the adverse effects of sportfishing gear and fishing actions on EFH as well.|22| In addition , NOAA The fishing industry and the FMCs may discuss and make recommendations to any state agency on their actions which may affect EFH.|23|
Most consultations are done inside the NMFS regional offices: Higher Atlantic Regional Fisheries Workplace (GARFO), Southeast Regional Workplace (SERO), West Coast Territorial Office (WCRO), Alaska Local Office (AKRO), and Pacific cycles Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State organizations and private landowners are not necessary to consult with NMFS. EFH consultations are required if the federal government possesses authorized, funded, or performed part or all of a proposed activity, and if the action will adversely affect EFH.|24| Detrimentally affecting EFH includes direct or indirect physical, chemical substance or biological alterations with the waters or substrate and loss of, or injury to species and their habitat, and other environment components, or reduction on the quality and/or quantity of EFH.
Natural environment areas of particular concern or perhaps HAPCs are considered high top priority areas for conservation, management, and research.|26| HAPCs are subsets of EFH that merit work because they meet in least one of the following 4 criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a habitat type that is/will come to be stressed by development;
will include a habitat type that is unusual.|27|
Current HAPCs involve important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, amongst other areas of interest. HAPCs are afforded the same regulatory security as EFH and do not banish activities from occurring inside the area, such as fishing, snorkeling, swimming or surfing.
Fundamental Fish Habitat is chosen for all federally managed fish under the MSA whereas Essential Habitat is designated meant for the survival and recovery of species listed as threatened or endangered beneath the Endangered Species Act (ESA).|29| Critical habitats include areas occupied by the threatened or endangered variety that include physical and biological features that are essential to the conservation of the species.|30| Critical Habitat can be designated as critical at that moment a species is listed beneath the ESA.|31| EFH and Critical Habitat will vary in terms of designation and control, but they may overlap for sure species such as salmon.|32|
Home characteristics include sediment type, type of bottoms (sand, silt and clay), structures root the water surface, and aquatic community structures. These case are essential for fish and ecosystem health. The fundamental environment structure begins with gunk. Erosion is stabilized simply by submerged aquatic vegetation. You will find two main types of bottoms, hard and soft.|33| A study by simply Christensen at el. (2004) looked at three bottom environment types (vegetated marsh advantage, submerged aquatic vegetation, and shallow non-vegetated bottom) with regards to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the research showed that brown prawn selected vegetated areas in salinities 15-25 ppt and so they would select vegetated areas over marsh edges when they co-occurred. Finding the areas that had the highest abundance helped to identify EFH of teenage brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom delivers hard complex vertical framework for attachment of a sponge, seaweed, and coral, which support a diverse reef fish community.|35| This kind of community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, many different fin-fishes, alga, and a sponge. Areas of compacted or sheered mud and sediment can also be a form of hard bottom.|36|
Soft bottom consists of unconsolidated sediment and unvegetated areas. In some regions soft feet are not protected even though they are often primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Qualities that affect soft bottom in relation to organisms that employ them include sediment grain size, salinity, dissolved breathable oxygen and flow.
